SURFACE MOUNT INDUCTORS
CHIP INDUCTORS
LQW1608A Series
The LQW1608 Series are miniaturized surface mount
inductors with an aluminum core bobbin. Murata’s unique
winding technology enables tight tolerances and high
Q values in the high frequency range. It also minimizes
stray capacitance, hence increasing the self-resonant
frequency. It is suitable for high frequency circuits in
telecom equipment.
